New computer, W11, completely updated. The old SATA SSD was removed from old PC, had W10 on it and that had FFx 133.0 installed; successfully transferred the bookmarks to another W10 PC but not the Passwords/logins. Transferred all the information from the Mozilla folder (per Firefox/Mozilla help) to a USB: plugged it into my new computer and did the same transfer of the Places, Key4, logins, and favacons to the new computer: no change. Just finished uninstalling FF and removing the Mozilla file from App Data, then doing a complete reinstall; then added the old places etc. to the new install. Nope, didn't work. So what's going on with FF and W11?? Is there a solution? I have been with Firefox now for over 10 years and have never had these kinds of problems moving my information.

So yea I've noticed opened Youtube tabs will just randomly start the video playing while I'm in another tab, it's really annoying. I've tried disabling all extensions but it continues to happen. Anyone know whats going on, it's been happening for a really long time.

Using Windows 11 Firefox version 133.0.

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

Win7x64p, FF 115.18.0esr (64-bit) When I power on my Dell E6440 from hibernate (& restart?), with or without some small portable apps running -Total Commander, notepad. I have to wait (sometimes 5 minutes or more) before I can use without significant lag. HDD LED full-on. If I start up FF while disk usage is very high, sometimes 1 core of CPU gets stuck at 100%. Sleep & wake resets this. Watching in Resource Monitor \Mozilla\xul.dll using high disk B/sec & HDD LED full on, when HDD LED returns normal xul.dll disk read activity drops to 0 or near.

Is a FF service/process reading its stored data?(via xul.dll) or something. Looking for any ideas to troubleshoot.

I'm not having any issues with FireFox running, just this process making PC unusable after wake-up. Thanks

Hello, A couple of months ago, I believe there was an update completed on Firefox and after that, I lost all of my bookmarks. I've since created a few, but the majority are gone. Is there any way to retrieve the bookmarks?

Thank you, Nicole Bechhold

Hi, I am in Australia and over recent months I have had trouble fully loading websites on FireFox. I have used FireFox on my laptop for many years but this issue has just emerged. I can open the same websites on Chrome and they open as fully functional ie, links are live, sign in options are available. Is there a reason why this is happening? The websites I tried to open on FireFox are important sites for me and I use them regularly. Is there something in settings that I need to change? I do not want to stop using FIreFox but I will have to change if I cannot access these websites. I have attached screen shots of one particular website on FireFox and Google Chrome. Kind regards Narelle
